How else is one supposed to interpret Georgie saying, verbatim, “If this really is a second chance, please try to take it. But I don’t think that it is.” There is no other way to take it but that she’s saying him coming back is not a second chance, meaning he’s back because of sinister reasons, and if he were human he should’ve and would’ve stayed dead. But because he didn’t, and because she thinks him staying dead would’ve been a sign he wasn’t a monster and made the right choice to not become one, she’s saying, “I wish you’d died.” I cannot interpret it as anything else by her saying that.
